Item type:Publication, Design and Build of a Multi-Zone Beamforming Speaker(2025-01-01); Recently, beamforming speaker for multi-zone sound production is an application that is of interest such as conference system, public address, home cinema, and gaming. This paper presents a design of a speaker array and DS beamforming aiming to use for product advertising such that the speaker can be installed on the shelf. The limit of the space and the usable frequency range are the challenges of this work. The design of the speaker cabinet and the beamforming algorithm will be discussed. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Iris recognition based on dynamic radius matching of iris image(2012-10-02); ; Matsuura, T.This paper presents iris recognition method based on dynamic radius matching of iris image. First, the iris images are segmented to remove the eyelashes and eyelids. Then the individual feature of the iris image can be extracted by expanding their polar images into Fourier series. The obtained Fourier coefficient is used as the individual features for iris recognition. Moreover, in order to reduce the fluctuation caused by size of pupil and iris, the dynamic radius matching is introduced to calculate the similarity between the iris images. Experimental results were performed on CASIA V1.0 [6] public iris database having 756 iris images from 108 persons. The obtained accuracy rate was 94.8%. © 2012 IEEE. - Some of the metrics are blocked by yourconsent settings
